1. A new and distinct Portulaca plant named `LAZPRT1612` as illustrated and described.
Description



[0001] Botanical designation: Portulaca umbraticola Kunth.

[0002] Cultivar denomination: `LAZPRT 1612`.

BACKGROUND OF THE INVENTION

[0003] The present invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca umbraticola Kunth, commonly known as Wingpod Purslane, and hereinafter referred to by the name `LAZPRT1612`.

[0004] The new Portulaca plant is a product of a planned breeding program conducted by the Inventor in Merano, South Tyrol, Italy. The objective of the breeding program is to create new vigorous and freely branching Portulaca plants with numerous unique and attractive flowers.

[0005] The new Portulaca plant is a naturally-occurring branch mutation of a proprietary selection of Portulaca umbraticola Kunth identified as code number 09/123-1, not patented. The new Portulaca plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Merano, South Tyrol, Italy during the spring of 2014.

[0006] Asexual reproduction of the new Portulaca plant by terminal cuttings in a controlled greenhouse environment in Merano, South Tyrol, Italy since the spring of 2014, has shown that the unique features of this new Portulaca plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

[0007] Plants of the new Portulaca have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

[0008] The following traits have been repeatedly observed and are determined to be the unique characteristics of `LAZPRT1612`. These characteristics in combination distinguish `LAZPRT1612` as a new and distinct Portulaca plant: [0009] 1. Outwardly spreading to creeping growth habit. [0010] 2. Vigorous growth habit. [0011] 3. Freely branching habit. [0012] 4. Freely flowering habit. [0013] 5. Red purple and yellow-colored flowers. [0014] 6. Excellent garden performance.

[0015] Plants of the new Portulaca can be compared to plants of the parent selection. Plants of the new Portulaca differ primarily from plants of the parent selection in flower color as plants of the parent selection have a less intense (lower contrast) flower color pattern that is unstable. In addition, plants of the new Portulaca are more freely branching and have larger flowers than plants of the parent selection.

[0016] Plants of the new Portulaca can be compared to plants of Portulaca oleracea `Kakegawa CY2`, disclosed in U.S. Plant Pat. No. 14,149. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of `Kakegawa CY2` in the following characteristics: [0017] 1. Plants of the new Portulaca are more compact than plants of `Kakegawa CY2`. [0018] 2. Plants of the new Portulaca are more creeping than and not as upright as plants of `Kakegawa CY2`. [0019] 3. Plants of the new Portulaca have larger flowers than plants of `Kakegawa CY2`. [0020] 4. Plants of the new Portulaca and `Kakegawa CY2` differ in petal color as plants of `Kakegawa CY2` have yellow-colored petals with purple-colored stripes.

[0021] Plants of the new Portulaca can also be compared to plants of Portulaca oleracea `Duet Red on Yellow`, not patented. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of `Duet Red on Yellow` in the following characteristics: [0022] 1. Plants of the new Portulaca are more compact than plants of `Duet Red on Yellow`. [0023] 2. Plants of the new Portulaca are more creeping than and not as upright as plants of `Duet Red on Yellow`. [0024] 3. Plants of the new Portulaca have larger flowers than plants of `Duet Red on Yellow`. [0025] 4. Flower color pattern of plants of the new Portulaca is more stable than flower color pattern of `Duet Red on Yellow`.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0026] The accompanying colored photograph illustrates the overall appearance of the new Portulaca plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Portulaca plant.

[0027] The photograph is a close-up view of a typical flowering plant of `LAZPRT1612`.

DETAILED BOTANICAL DESCRIPTION

[0028] The aforementioned photographs and following observations, measurements and values describe plants grown in 13-cm containers during the spring and summer in an outdoor nursery in Merano, South Tyrol, Italy and under cultural practices typical of commercial Portulaca production. During the production of the plants, day and night temperatures ranged from 13.8.degree. C. to 28.6.degree. C. and light levels ranged from 60 to 70 klux. Plants were four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
